After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Sweep the codebase for common typos. Includes some changes to visible function
names that were misspelt.

This enables IO error reports in both the child and server processes.
The scheme still isn't entirely satisfactory and output is jumbled but it beats
having no output at all. This will hopefully unblock ARM support (PR18057).

The client and server now use a single unified low-level RPC core built around
LLVM's existing cross-platform abstractions.

Eliminates the LLI_BUILDING_CHILD build hack from r199885.
Also add a FIXME to remove code that tricks the tests into passing when the
feature fails to work. Please don't do stuff like this, the tests exist for a
reason!

Eliminate the copies LLVM's System mmap and cache invalidation code. These were
slowly drifting away from the original version, and moreover the copied code
was a dead end in terms of portability.
We now statically link to Support but in practice with stripping this adds next
to no weight to the resultant binary.
Also avoid installing lli-child-target to the user's $PATH. It's not meant to
be run directly.

The execution code path crashes if it can't execute the binary so we might as
well take precautions here.

MCJIT remote execution (ChildTarget+RemoteTargetExternal) protocol was in
dire need of refactoring. It was fail-prone, had no error reporting and
implemented the same message logic on every single function.
This patch rectifies it, and makes it work on ARM, where it was randomly
failing. Other architectures shall profit from this change as well, making
their buildbots and releases more reliable.

root path to which object files managed by the LLIObjectCache instance should be
written. This option defaults to "", in which case objects are cached in the
same directory as the bitcode they are derived from.
The load-object-a.ll test has been rewritten to use this option to support
testing in environments where the test directory is not writable.

I believe the bot failures on linux systems were due to overestimating the
alignment of object-files within archives, which are only guaranteed to be
two-byte aligned. I have reduced the alignment in
RuntimeDyldELF::createObjectImageFromFile accordingly.

- Mark tests as XFAIL:cygming in test/ExecutionEngine/MCJIT/remote.
Rather to suppress them, I'd like to leave them running as XFAIL.
- Revert r193472. RecordMemoryManager no longer resolves __main on cygming.
There are a couple of issues.
- X86 Codegen emits "call __main" in @main for targeting cygming.
It is useless in JIT. FYI, tests are passing when emitting __main is disabled.
- Current remote JIT does not resolve any symbols in child context.
FIXME: __main should be disabled, or remote JIT should resolve __main.

This fixes a problem from a previous check-in where a return value was omitted.
Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing. Those tests attempt to link against an external symbol and remote symbol resolution is not supported. The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice. With this check-in remote symbol resolution fails, and so the test (correctly) fails.
